12836 Federal Register / Vol. 89, No. 34 / Tuesday, February 20, 2024 / Notices 

the regional water quality control boards 

and the State Department of Toxic 

Substances Control to control the 

mobilization of contaminants and 

mitigate impacts. 

Decision 

The continued operation of LLNL is 

critical to NNSA’s Stockpile 

Stewardship and Management Program, 

to prevent the spread and use of nuclear 

weapons worldwide, and to many other 

areas that may impact national security 

and global stability. NNSA has decided 

to implement the Proposed Action. The 

Proposed Action will enable NNSA to 

fulfill its statutory missions and other 

responsibilities, considering economic, 

environmental, technical, and other 

factors. 

Basis for Decision 

The Final SWEIS provided the NNSA 

decision-maker with important 

information regarding the potential 

environmental impacts of alternatives 

and options for satisfying the purpose 

and need. In addition to environmental 

information, NNSA also considered 

public comments, statutory 

responsibilities, strategic objectives, 

technical needs, safeguards and 

security, costs, and schedule in its 

decision-making. 

Mitigation Measures 

No potential adverse impacts were 

identified that will require additional 

mitigation measures beyond those 

required by regulations, permits, and 

agreements or achieved through design 

features or best management practices. 

However, if mitigation measures above 

and beyond those required by 

regulations, permits, and agreements are 

needed to reduce impacts during 

implementation, they will be developed, 

documented, and executed. Because no 

new potential adverse impacts were 

identified that will require additional 

mitigation measures beyond those 

required by regulation or achieved 

through design features or best 

management practices, NNSA does not 

expect to prepare a Mitigation Action 

Plan.

I. Executive Summary 

A. Does this action apply to me? 

This action provides information that 

is directed to the public in general. 

B. What action is the Agency taking? 

This document lists the statements of 

findings made by EPA after review of 

submissions under TSCA section 5(a) 

that certain new chemical substances or 

significant new uses are not likely to 

present an unreasonable risk of injury to 

health or the environment. This 

document presents statements of 

findings made by EPA during the 

reporting period. 

C. What is the Agency’s authority for 

taking this action? 

TSCA section 5(a)(3) requires EPA to 

review a submission under TSCA 

section 5(a) and make one of several 

specific findings pertaining to whether 

the substance may present unreasonable 

risk of injury to health or the 

environment. Among those potential 

findings is that the chemical substance 

or significant new use is not likely to 

present an unreasonable risk of injury to 

health or the environment per TSCA 

section 5(a)(3)(C). 

TSCA section 5(g) requires EPA to 

publish in the Federal Register a 

statement of its findings after its review 

of a submission under TSCA section 

5(a) when EPA makes a finding that a 

new chemical substance or significant 

new use is not likely to present an 

unreasonable risk of injury to health or 

the environment. Such statements apply 

to PMNs, MCANs, and SNUNs 

submitted to EPA under TSCA section 

5.

(which includes import) a new chemical 

substance for a non-exempt commercial 

purpose and any manufacturer or

1 In the Wet Weather Water Quality Act of 2000, 

Congress added section 402(q) to the CWA to 

provide that each permit, order, or decree issued 

after December 21, 2000, for a discharge from a 

municipal combined storm and sanitary sewer shall 

conform to the 1994 Combined Sewer Overflow 

Control Policy (33 U.S.C. 1342(q)(1)). 

2 In the Water Infrastructure Improvement Act 

(H.R. 7279), Congress added section 402(s) to the 

CWA that defines an Integrated Plan as one 

developed in accordance with the 2012 Integrated 

Municipal Stormwater and Wastewater Planning 

Approach Framework; and requires the EPA to 

inform municipalities of the opportunity to develop 

an Integrated Plan that may inform permit terms 

and conditions to help meet their existing CWA 

obligations (33 U.S.C. 1342(s)). These amendments 

clarified that municipalities may develop an 

Integrated Plan as defined under the CWA and the 

permitting authority may develop NPDES permit 

terms and conditions informed by that plan. 

processor wishing to engage in a use of 

a chemical substance designated by EPA 

as a significant new use must submit a 

notice to EPA at least 90 days before 

commencing manufacture of the new 

chemical substance or before engaging 

in the significant new use. 

The submitter of a notice to EPA for 

which EPA has made a finding of ‘‘not 

likely to present an unreasonable risk of 

injury to health or the environment’’ 

may commence manufacture of the 

chemical substance or manufacture or 

processing for the significant new use 

notwithstanding any remaining portion 

of the applicable review period. 

D. Does this action have any 

incremental economic impacts or 

paperwork burdens? 

No. 

II. Statements of Findings Under TSCA 

Section 5(a)(3)(C) 

In this unit, EPA provides the 

following information (to the extent that 

such information is not claimed as 

Confidential Business Information 

(CBI)) on the PMNs, MCANs, and 

SNUNs for which, during this period, 

EPA has made findings under TSCA 

section 5(a)(3)(C) that the new chemical 

substances or significant new uses are 

not likely to present an unreasonable 

risk of injury to health or the 

environment: 

The following list provides the EPA 

case number assigned to the TSCA 

section 5(a) submission and the 

chemical identity (generic name if the 

specific name is claimed as CBI).

Draft Guidance for Future National 

Pollutant Discharge Elimination 

System (NPDES) Permitting of 

Combined Sewer Systems 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice; request for comment. 

SUMMARY: The U.S. Environmental 

Protection Agency (EPA) is seeking 

comment on this draft Guidance to 

clarify and inform future National 

Pollutant Discharge Elimination System 

(NPDES) permitting actions for 

communities with combined sewer 

systems. This draft Guidance highlights 

the available approaches for permitting 

combined sewer overflow (CSO) 

communities nearing completion of the 

projects and activities identified in their 

Long-Term Control Plan (LTCP). The 

draft Guidance summarizes options 

under the Clean Water Act (CWA) that 

are articulated in the 1994 Combined 

Sewer Overflow Control Policy and the 

option to use the EPA’s 2012 Integrated 

Planning Framework to look holistically 

at future investments in controlling 

wastewater and stormwater discharges 

and improving water quality. 

DATES: Comments must be received on 

or before March 21, 2024.

SUPPLEMENTARY INFORMATION: 

Supporting Documentation. The docket 

contains supporting materials that were 

referenced in the development of this 

Guidance. 

I. Executive Summary 

The Combined Sewer Overflow (CSO) 

Control Policy (CSO Policy) was issued 

in 1994 and incorporated into the Clean 

Water Act (CWA) in 2000.1 Since its 

issuance, communities with combined 

sewer systems nationwide have made 

substantial progress toward the goals 

established in the CSO Policy. During 

this same time, many factors that 

influence how communities address 

CSOs have evolved. Recognizing these 

ongoing changes and to aid 

communities addressing multiple 

municipal CWA requirements, in 2012, 

the EPA developed an Integrated 

Planning Framework that clarifies CWA 

flexibilities and offers a voluntary 

opportunity for a municipality to 

prioritize and sequence, where 

appropriate, those infrastructure 

projects that provide the greatest or 

fastest environmental and public health 

benefits. Integrated planning was added 

to the CWA in 2019.2 The EPA is issuing 

this draft Guidance to clarify and inform 

future National Pollutant Discharge 

Elimination System (NPDES) permitting 

actions for communities with CSOs. 

This draft Guidance would be 

applicable to permitting actions once 

the CSO permittee has completed 

construction of CSO controls and 

demonstrated that they are achieving 

the performance objectives outlined in 

their Long-Term Control Plan (LTCP). 

The draft Guidance is intended to
